The NSR and RS Chassis can work pretty well here. The NSR is very good for most of the track. There are two turns that are pretty tight on the RS but can be done. I have ridden both bikes on the track and found them to work well. Cam are you looking at the track configs NWGP runs? I would say if you are the Long or short 90 config would probably work best for most of the bikes.
Long 90 -
Short 90 -
